IMO large tattoos,like full back or full leg or arm sleeve are a sign of the times, large tattoos are a part of the new tattoo world we live in,
social media has also changed the tattoo world,
when I started getting tattooed in the early 80's, it was all small pieces,
back when I started you walked into a shop on a Friday night,picked a flash off the wall,and waited for your turn,
I have one large tattoo,but all the rest I have are small to medium size,
to each his own,
but personally I like the traditional look of many small tattoos,
